Ok it is time for my dumb question on the day

It regulates the voltage from the power supply to the individual components with in the pre-amp.

Theo what effects doe's it have on the preamp? what causes it to happen?
Let me know
Thanks

Regulators are good for several reasons. If the supply voltage to a stage sags in use then then the stage is drawing more current than the supply can continously supply, and this may be audible. A well designed regulator will also by definition keep noise from the power supply out of the amplifier circuits.

The regulator in effect acts like a giant capacitor to maintain the voltage and reduce noise.

Harnellt,

Think of it like the "cruise control" on your car.

You set your cruise control to 45 MPH, and your car is
starting to climb a hill. It will naturally tend to slow
down going up hill. The cruise control will open the
throttle to produce more engine power for the heavier
load of climbing the hill. That way you don't slow down
going up the hill.

When your music demands more power to drive the amplifiers
in your preamp - the regualator makes sure the heavier
load doesn't drag down the voltage. It, in essence, lets
more power into the system to handle the heavier load.

That's about as good an analogy as I can think of at the
moment.
